Abstract
A display system includes: a screen in which, in an area on which invisible light is incident, a scattering state where visible light is scattered and a transmission state where visible light is transmitted are switched; an image projection system to project an image of the visible light onto the screen; and an invisible light projection system to project the invisible light onto the screen and to cause an area of the screen onto which a desired portion of the image is projected to have the scattering state.

A display system comprising:
- a screen in which, in an area on which invisible light is incident, a scattering state where visible light is scattered and a transmission state where visible light is transmitted are switched;
- an image projection system to project an image of the visible light onto the screen;
- and
- an invisible light projection system to project the invisible light onto the screen and to cause an area of the screen onto which a desired portion of the image is projected to have the scattering state.
A screen comprising an area on which invisible light is incident, wherein in the area, a scattering state where visible light is scattered and a transmission state where visible light is transmitted are switched.
A projector for displaying an image on a screen in which a scattering state where visible light is scattered and a transmission state where visible light is transmitted are switched in an area on which invisible light is incident, the projector comprising:
- an image projection system to project an image of visible light onto the screen;
- and
- an invisible light projection system which projects invisible light onto the screen and brings an area of the screen onto which a desired portion of the image is projected into the scattering state.
